Washing liquid supplier
Abstract
A washing liquid supplier includes a container filled with
washing liquid, a pumping chamber formed in a cylinder under the
container and defined by a suction valve formed on the lower
opening of the container, a discharge valve formed on the lower
portion of the pumping chamber and a nipple button, and a discharge
pipe horizontally formed under the discharge valve. The nipple
button may be depressed to boost the washing liquid through the
discharge pipe into user's hand. The depression of nipple button
and pick-up of the liquid can be done at the same time by the
single hand of the user for convenient operation.

Claims
I claim:
1. A washing liquid supplier comprising: a container filled with
washing liquid and formed with two holding grooves to engage with
two hooks of holding bracket fixed on a wall, said container having
an opening;
a valve means fixed under said container; and a discharge pipe,
horizontally fixed under said valve means and formed with a rear
extension to terminate on the fixing wall and terminated on its
front end with a resilient sealer to resiliently seal a discharge
opening formed on the end of said pipe;
the improvement comprising: said valve means including an outer
cylinder upperly connected with said container and lowerly
connected with said discharge pipe; and inner cylinder formed
within said outer cylinder and in communication with said discharge
pipe; an upper valve seat formed in said container opening; a lower
valve seat formed in said inner cylinder; a suction valve pivotedly
and upwardly sealing against said upper valve seat; a discharge
valve resiliently and upwardly sealing against said lower valve
seat; said inner cylinder, said suction valve, and said discharge
valve difining a pumping chamber;
a side arm portion transversely communicated with said inner
cylinder;
a cap having a centrally formed button hole, said cap being
attached to said side arm portion;
a resilient nipple button extending through said button hole and
mounted between said side arm portion and said cap, whereby said
nipple button is depressed to boost washing liquid in said pumping
chamber through said discharge pipe into the user's hand for direct
and convenient use.
Description
BACKGROUND OF THE INVENTION
A conventional container filled with washing liquid or detergent
provides an actuating handle atop on the container, which can be
depressed to discharge fluid downwards for washing use. It is
inconvenient for the user since the actuating handle is operated by
user's one hand and the discharged liquid should be picked up by
his another hand.
The present inventor has found such an inconvenience defect of
conventional container for washing liquid and invented the present
washing liquid supplier.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a washing liquid
supplier comprising a container for liquid, a valve means and a
discharge pipe horizontally fixed under the valve means, wherein
the valve means is actuated to pump liquid from the container,
through the discharge pipe, for directly flowing into user's hand
for convenient use.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an illustration when fixing the present invention on a
wall.
FIG. 2 is a partial sectional drawing showing the depression of
present invention for discharging washing liquid.
FIG. 3 shows the release of a resilient button of the present
invention.
DETAILED DESCRIPTION
As shown in the Figures, the present invention comprises: a
container 1, a valve means 2 and a discharge pipe 3.
Container 1 is formed with a filling hole 11 atop on the container
for refilling washing liquid. Two holding grooves 12 are formed on
the container to engage with two engaging hooks 131 formed on a
holding bracket 13 which may be adhered or fixed on a wall W as
shown in FIG. 1. A male-threaded portion 14 is formed on the lowest
portion of container 1 to connect the valve means 2.
Valve means 2 comprises an outer cylinder 21 connecting the
container 1 and the discharge pipe 3, an inner cylinder 22 formed
within the outer cylinder 2, a suction valve 23 pivotedly and
upwards sealing an upper valve seat 24 formed on the opening as
defined by the male-threaded portion 14, a discharge valve 26
resiliently and upwards sealing a lower valve seat 25 formed on the
lower portion of a pumping chamber 22a, a side arm portion 27
transversely connected with pumping chamber 22a, a cap 29
terminated on side arm portion 27 and a resilient nipple button 28
extending through a button hole centrally formed on cap 29.
Outer cylinder 21 is formed with an upper female-threaded portion
211 to connect the male-threaded portion 14 of container 1 and
formed with a lower male-threaded portion 212 to connect the
discharge pipe 3. Inner cylinder 22 is formed with an upper holder
221 for inserting the central extension 242 of valve seat 24
positioned under container 1. Valve seat 24 is lowerly formed with
a suction hole 241 to communicate with the pumping chamber 22a
within the inner cylinder 22. The valve seat 24 is also formed with
an outer extension 243 which serves as a packing for
female-threaded portion 211 and male-threaded portion 14. The inner
cylinder 22 is lowerly formed with a bottom plate having a central
hole 222 for fixing valve seat 25. Discharge valve 26 is backed by
a restored spring 261 riding on a spring socket 35 on pipe 3. The
resilient nipple button 28 is internally formed with an extension
281 which is fixed between side arm portion 27 and cap 29 for
packing purposes. Side arm portion 27 is formed with a central
hollow portion 271 for pumping action. The pumping chamber 22a
within inner cylinder 22 is defined among said upper suction valve
23, said lower discharge valve 26 and said nipple button 28.
Discharge pipe 3 is formed as a horizontal pipe 30 under valve
means 2 and formed with a female-threaded portion 31 to connect
with outer cylinder 21 and formed with a holder 33 to fit the
lowest portion of inner cylinder 22. A rear extension 32 is formed
on the rear portion of pipe 3 to terminate on a fixed wall W
prevent from drop due to eliminate the twisting gravity force or
when depressing the button 28. Pipe 3 is formed with a discharge
hole 34 to lead liquid from valve means 2 into pipe portion 30.
Pipe portion 30 is terminated on its front end with a resilient
sealer 36 which may be made with rubber or rubber-like material to
resiliently seal the discharge opening 361 formed on the end
thereof.
When using the present invention, the button 28 is depressed to
pump the washing liquid L to chamber 22a by closing valve 23 and
opening the valve 26 to discharge fluid through pipe 30 and opening
361 for washing use. When releasing button 28, the pressure in
chamber 22a is reduced and the valve 23 is opened to suck fluid in
container 1 into chamber 22a and the valve 26 will as restored by
spring 261. The resilient sealer 36, if not under pressure, will
automatically seal the opening 361 for hygienic purpose.
